MORTAR-BED FOR STAMP-BATTERIES.

SPECIFICATION forming part of Letters Patent No. 310,296, dated January6, 1885.

Application filed May 2'7, 1884. (No model.)

To all whom it may concern.-

Be it known that we, Gnonen Massu and FILoMENo FERNANDEZ, of Mazatlan,in the Republic of Mexico, have invented certain Improvements inMortar-Beds for StampBatteries; and we hereby declare the following tobe a full, clear, and exact description thereof.

()ur invention relates to the class of orecrushing devices orstamp-batteries, and more particularly to certain new and usefulimprovements in the mortar-beds thereof, whether of single or doubledischarge or dry or wet crushing mortars.

Our invention consists in improved means for adjusting the screens ofmortar beds, whereby they are adapted to be raised and lowered accordingto the state of the dies, whether new or worn out, all of which we shallhereinafter fully describe and claim.

The object of our invention is to so arrange the screens that they maybe raised for new dies or lowered as the said dies wear out, in

. above the dies, and that the discharge of the pulp may be effected tothe best advantage, as we shall presently fully indicate.

Referring to the accompanying drawings, Figure 1 is a sectionalelevation of our mortar-bed, taken on the line 00 at, Fig. 2, the dieand stamp-head being in elevation. a plan of the mortar-bed. Fig. 3 is afront view of mortar-bed. Fig. 4 is a front view of movable oradjustable plate with screen,brackets, trough, &c. Fig. 5 is a sectionthrough line 3 3 Fig. 4. Fig. 6 is a top view of Fig. 4.

Z is the mortar-bed, containing the die 2. Y is the frame of thebattery; X, the stamp, and IV the stamp-stem.

By reference to Fig. 1 it will be seen that we leave the n1ortarbed openin front at a, the mortar here shown having a single discharge. In caseof a double discharge the mortar would be left open both in front andback, and all the parts,which we shall herein describe as applicable tothe single discharge,

would have to be duplicated for a double-discharge battery. In the openfront of the mortar we leave but a toe, A, across it to hold the dies inplace. The screen 0 rests on the top edge of a wrought-iron movable oradjustable plate, B, which is dressed or faced v on the Fig. 2 isplaner, as also 'is the face Q of mortar-bed. Both the screen andmovable plate are held water-tight against the mortar-bed by thefollowing means:

First. By two wedges, F, Figs. 1, 3, two angle-irons, D, and twocast-iron slides or guides, I, planed and riveted to the jaws B, Fig. 2,extending from the mortar and to the housing, which housing may be madeeither of sheetiron or cast together with mortar-bed proper. In order tosecure the tightening of the wedges F equally against the screen andmovable plate, the latter is provided with two cast-iron liners, K, (seeFigs. 4 and 5,)planed and riveted to the plate, in order to make up forthe difference of thickness between the frame of the screen and themovable plate.

Second. By three screws, G, fitted with small wheels or spurs 9, Fig. 1.These screws work into a cast-iron Crosspiece, L, held between theprojecting jaws R of mortar, Fig. 3.

By means of a yoke, T, andscrew S, working through a nut, M, fitted in abracket, V, the movable plate and screen can be lowered or raised. ThebracketVis open in front and provided with a pin to prevent the yokefrom falling off, and the extremities of the legs of yoke are made tofit into two cast-iron brackets, H, Figs. 3 and 6, riveted to themovable plate, Fig. 4. Said plate bears also in its center a smallwrought-iron bracket, I, and wedge i,to tighten the screen against theplate. (See Figs. 6, 5.) After the screen has been regulated accordingto height of dies, the yoke, nut, and bracket can be taken out byremoving the above-namedparts,tobe replaced again when a new setting ofthe screen is required. The trough N is riveted to movable plate toreceive the pulp, which is afterward delivered to tanks through roundcast-iron spout O.

In Fig. 1 the screen is represented as being at a proper height abovethe die, and the oband yoke for raising and lowering said screen,substantially as and for the purpose herein described.

2. The combination, in an ore-crushing battery or stamp-mill, of themortar-bed,open or cut away at its discharge, a screen at saiddischarge, and a screw and yoke for raising and lowering saidscreen,whereby its height above the dies in the mortar-bed may bemaintained, whether said dies be new or worn, substantially asdescribed.

3. The combination, in an ore-crushing bat tery or stamp-mill, of amortar-bed, Z, open 1 at its discharge a, and having a toe, A, acrossthe discharge, the die a, a suitable screen covering thedischarge,and'a' screw and yoke for raising or lowering it in the open space a,substantially as described.

4. The combination, in an ore-crushing battery or stamp-mill, oiamortar-bed, Z, die c, the movable plate B, and screen 0, secured to itstop,wedges F, angle-ironsD,and guides P, for holding said plate andscreen against the mortar and frame of the battery, and a screw and yokefor raising and lowering them, substantially as and for the purposeherein described.

5. In an ore-crushing battery or stamp =mill,

a mortar-bed, Z, having projecting arms It and die 2 the movable plate13, having liners or strips K, and the screen 0, secured to the top ofplate, in combination with the means for holding said plate and screenin place, consisting of the wedges F, angle-irons D,'and guides P,riveted to arms R and to the housing of the mill, the tightening-screwsG, and cross-piece L, said screws having wheels or spurs 9, bearingagainst said plate B, substantially as described;

6. The combination, in an ore-crushing battery or stamp-mill, of amortaubed, Z, die a, the movable plate B, and screen 0, secured to itstop, means for holding said plate and screen against the mortar-bed overits dis charge, and the mechanism for raising and lowering them,consisting of the yoke T, bearings or brackets H on the plate B, thescrew S, nut M, and bracket V, secured to the frame ,of the mill,substantially as herein described.

In witness whereof we have hereunto set our hands.
